Be it known that l, CrrAnLns Dwnion MCC-inn, av citizen ot the United States, and a resident ot Atlanta, in the county ot Fuln ton and State ot Georgia, have invented cer tain nev.'Y and uset'ul improvements in lfloppers tor lleating- Pipes, ot Whieh the tollen ing; is a speciiication. y lfy invention relates to improvements in heating and ventilating systems, and it consists in the constructions and combinations herein described and claimed.

ein object oit the invention is to provide a hopper in the nature ot al catch-all to be applied to heating and ventilatinp; pipes in such a ma iner as to catch such dirt and other matter as may tall into the pipes through the tloor grating.

it "further object ot the invention provide a hopper ot' such a as ce* readily attached to enistiiugv heatn Ventilating pipes Without the neces,.-..y ot even taking' such pipes down tor the purpose ot installation.

A 'further object ot the invention is to provide a hopper With an outlet door which is capable oit being opened and closed trom the floor above so as not to make it necessary Y to go into the basement to accomplish this purpose.

Another object ot the invention is to design the hopper in such a` manner that all material collected thereby Will gravitate toward the bottom whence it may be removed through a door at the side.

Other objects and advantages will appear in the following specitication. reference being had to the accernpanj/Jing drawing, in which:

plate which is used When a` chain pull is e. ployed in connection with the door, and

Fig'. is a detail section illustrating the ,ngement of the floor plate. he purpose. ot the invention is to prohopper or catch-all l which, as the vide a name implies, is designed to catch all ot the irt and other 'foreign matter which might il through the graft-ing` 2 ot the hot air or rontilatingr pipe 3. The invention is adapted more particularly tor use on such pipes as discharge the hot air into a room through the tloor. i

According to such systems a register 4 is used for the purpose oi regulating the influx of the air. Sweepings and other dirtfinding' its Way into the register l usually accumulates along the pipe 3 and establishes avery nnsanitary condition. Instead ot allrivving such dirt to find its Way directly into the pipe 3, the hopper l is provided to intercept the dirt and make it easy to remore it when required. The pipe 3 is thus kept in a clean and sanitary condition.

The sides 5 and rear Wall 6 ot the hopper l taper to a relatively narrow chamber 7 (Fig. 5) in 'which all ot the dirt accumulates due to the shape ot the Walls. rlhe remaining Wall 8 is straight and utilized tor the mounting` at 9 ot a door l0 which can be raised either by means ot the cable 1l in Figs. l and 2 or the chain l?. in Figs. 6 7.

In the former instance the cable is provided with a ring 13 which adapted to be hang; on any ot a plurality ot hooks llt in the wall adjacent to the register, this ar rangement being' tor the purpose ot adjusting; the amount ot opening et the door l0 in places Where the hopper is utilized as tresh air intake. rlhe reader can readily conceive that the use ot the hopper is not contined to catching); accumulations ot dirt. Situations may arise Where 4the Yfurnace furnishes too much heat to the room. By simply raising` the door 10 slightly, enough cold air may be admitted to temper the hot air to a` comtortable degree, the hooks ll serving as ad- `iusting` means for varying the amount of opening ot the door. The cable ll is run over one or more pulleys l5.

er spring7 16, coil-ed about the bearingpin 9 ot the door 10 serves to keep the door closed in place over the mouthpiece 17. The mouthpiece includes a semi-circular flange 18 which as shown in Figs. l and 4, surrounds a portion ot' the lower end oi the chamber 7, not only to enable mounting the mouthpiece to better advantage but also to aid in supporting the load on the hopper.

rThe hopper includes a :tlange 19 at the top which is useful in applying the hopper over the opening 20 in the pipe 3. it. number oiI bolts 2l are used in fastening the hopper to the pipe, and in practice, the whole will be covered with asbestos or other insulating material, for the purpose ot excluding cold air and checking the radiation of heat 'from the pipe 3. it is to be observed that the general shape ot the sides S and. the back 6 tends to move any material which might tall into the hopper toward the opening 22 in the remaining straight wall 8. This particular arrangement insures the discharge ot all accunuilations from the hopper when the door l0 is opened from the floor above. .er slight modification in the means of opening the door and holding it to its adjusted position is disclosed in Figs. 6 and 7 wherein a floor plate 23 is made use of. This floor plate has an opening 24 shaped very much like a keyhole in that the opening has a circular portion and also a narrow slotted portion. The circular portion permits the free movement of the chain l2 and adjustments are made by simply sliding any one of the links into the narrow portion sidewise, the link next above furnishing a stop which holds the door in any position in which it may be at that time. A collar 25 extends through the floor and provides a smooth, unobstructed passage for the cha-in. Although the drawing illustrates a round pipe 3 which is described as a hot air pipe, it is to be understood that the principle of the invention is applicable to pipes it'or other purposes, for example, ventilating and cold air pipes, and may be ot other shapes, tor example, square, hexagonal, oval, etc.

While the construction and arrangement of the improved catcheall or hopper as herein described and claimed, is that oi a generally preferred form, obviously modifications and changes may be made without departing from the spirit ol the invention or the scope of the claims.

I claim:

l. In combination with a pipe discharging into a register, a hopper .arranged to catch foreign matter falling through the register and so prevent the clogging of the pipes, a door closing an opening in the lower extremity of said hopper, and means embodied in the shape ot the hopper causing said matter to accumulate adjacent to the door.

2. ln combination with a pipe discharging into a register', a hopper arranged to catch foreign matter falling through the register and so prevent the clogging of the pipes, a door closing an opening at one side of: the lower extremity oit said hopper, 'means embodied in the shape oi the hopper causing said matter to accumulate adjacent 'to the door, and means to actuate the door lrom a floor above.

3. in combination with the hot air pipe olf a 'furnace discharging into a register, a hopper atiixed over an opening .in said pipe to accumulate foreign matter falling through the register, a. door at one extremity oit the hopper, and means to either actuate the door from a-.distance to discharge said material or open the door to various predetermined distances to admit cold air into said pipe.

4. A hopper to be atiixed over an opening in a hot air pipe which discharges into a register, said hopper comprising a perpendicular front wall with a side opening, side and rear walls tapering downwardly to a comparatively narrow chamber to thereby accumulate foreign material behind said opening, a door closing the opening and retaining said foreign material, and means to actuate the door to enable the discharge of said material.

5. A hopper for the purpose described having a perpendicular front wall with a side opening, side and rear walls tapering toward said opening to form a substantially narrow chamber therebehind, a mouthpiece fixed to the front wall over said opening including a semi-circular flange extending beneath said chamber to strengthen the construction, a door hinged on said 1nouthpiece, a spring to keep the door closed, and means to actuate the door troni a distance, including means by which said actuating means can be adjusted and in turn vary the amount oit opening of said door.
